My invention relates in general to a building form and has more particular reference to an improvement in building forms of the type described in my prior United 5 States Patent, Number1,6'36,396.

The type of building form to which this invention applies is that used in connection with the construction of monolithic walls, and thev like, which are formed of concrete @'10 or similar material which is arranged to form a wallwhen in plastic condition and then allowed to Vharden or set, building forms being used to supportthe material in position till the material hardens, and

'a 15 forms a self-supporting wall. Such Walls are yusually built in coursesthat is to say, the wall is builtup 'to a convenient height,

l which is limited by the size of the forms, f and as soon as the material lhas set sufiiciently, the forms are removed and arranged at the top of the wall to support-the wall material of the new course till it hardens.

The forms are then removed and again aryranged'at the top of ,the wall to accommor 25V date the succeeding course. i

I It will be readily appreciated that, to construct a wall,verticalV throughout its entireV height, the yforms mustbe carefully adjusted as each course is Jformed. Such adiustment costs, and has heretofore beenregardedas unavoidable. It is mydesire `to provide a self-aligning form, the use otV whichwill eliminate the necessity of using eXtreme 35j care and accuracy during adjustment of the ing form. s y l till another important object of the invenftion is the provision, in a building form, having actielrod for securing the sides of the form in spaced relationship and Asupporting ythe samein position on a wall to receive building material, oi a form'clamp requires time and care, increases building.

the top of the wall.

adapted to align the sides oi the form and also to form a groove across the top ot the building material While supported by the form, which groove is shaped to engage and adapted to support the tie rod and to maintain the same and the building form in proper alignment on the wall.

Numerous other objects and advantages of the invention will be apparent as it 'is better undersood from the following description, which, taken in connection with the accompanying drawings, discloses a pres" erred embodiment of the invention.

Referring to the drawings:

Figure l is a perspective view of a wall during construction showing building ,forms of my invention in position thereon;

' Figure 2 is a perspective view similar to that of F iUure l the buildin r forms having D 7 b D been removed after thesetting of the course;

Figure 3 is a vertical cross section taken substantially along the line 3 3 in Figure 4; and y Figure 4 is a vertical cross section taken substantially along line L -4f of Figure l.

ATo illustrate my invention, I have shown on thev drawings theV upper portions of a wall l1, under construction by the so-called course method. A freshly poured course 13` is shown at the top of the wall l1, supported between building forms. These forms comprise a series ot' co-operating sections 15 which are secured in position on opposite sides of the completed wall l1, and extend upwardly therefrom in parallel relationship, being secured in position on the Wall by means of tie rods 17, the ends of which pass through registering apertures 33 formed in thev sides of co-operatinav sccf tions 15, near the lower edges thereof. Each tie rod rests in al groove 63 formed across The groove G3 is formed, as will be hereinafter more fully explained, in such a manner that it has a'deniteangular relationship with the vertical 'wall surface. In the preferred embodirnent shown, the groove is perpendicular to the wall surface.

Each form section 15 comprises a substantially rectangular tace plate 21', having Y io angle irons 23 of substantially T-shaped cross section arranged along the upper and lower edges of the face plate 21 for the purpose of strengthening the same. The top portion 24 of the l engages the surface of the face plate and the shank or body 26 forms a flange extending outwardly from Vthe face plate. Both the upper and lower angle irons of each section 15 extend laterally beyondV a side edge of the face plate 21 to engage the tace plate of the adjacent section, the abuttingend of the angle iron 23 of the adjacent section being cut away at3O to receive the' said extended end of the angle iron. The body 26 of the angle ironsalso are extended in both directions beyond the edges of the face plate and one said 'extended'` end 31 is offset as at 25 to overlap the opposite extended end 32 of the flange of the adjacent section. These extended portions'are apertured to receive pins 27 which secure the ianges of adjacent form sections together.. Angle irons 28 of substantially L-shaped cross section are'secured alongthe end edges of the face plate 2l, candvintermediate angle irons 29. of U.- shaped cross section are arranged across the face plate between the'v top and bottom angle irons 23'for the purpose of strengthening the form section. yTheanglefirons23, 28

and 29 may be secured to the faceplate andl to each lother] in anyA convenientr manner, such as byv spot welding, or the like, or by rivets. V'lhetie rod apertures 33 arevformed in the section through thevjlowfer ends of the U-shapedangle irons 29,'the top 24 of the lower angle iron 23, and the face plate, and accommodate the tie rods Awhich extendl between' the co-operating orm sections to secure the same ruponthe wall. The tie rods are provided witha plurality of spaced diametral holes 35 extending fromv one end to adjacent the mid'portions ot the rod, and the opposite end of the rod 15 is threaded for engagement witha nut The diametral holes25 are formed to receive a pin 36 adaptedtov engage. one section. The rod thenceextends across the wall and through the co-operating section, which is secured to the tie rod by means-of the nut 37. 'j The tie rods lie inthe grooves 63, which, being formed at right angles to the wall surfaces,

Yallow lthe rods to support the `form sections in definite' relationshipl on the' wall.

The upper portions of co-operatingform.y sections are maintained in spaced relation-I ship` by means of the `form clamp 19 which comprises a fbar 39 having an integral arm 41. arranged at onefend. The bar 39 is adapted to carrya slide' 45 having an integral arm 43 similar tothe arm 41. The

bar 39 is provided wit-ha series of spaced holes having aspacing similar yto that of lthe diametral holes 35 in the tieV rod, and

the slide l45 isYV provided with apertures 49 adapted to receive a bolt and nut 51 in position toY engage a desired one of the spaced holes 47' in vorder to secure the slide 45 in a desired position on the bar 39, according to the width of thefwall beingbuilt. The

bar 39 is provided with a notch 53 adjacent the arm 41 and the slide 45 is provided with c notches embrace the upper edges of the form sections when the clamping -bar asv sembly is arranged in position thereon. 1n-

asmuch as 4theform sections may rock with respect to the wall'to which they are mounted, the upper'edges of the form sections must necessarily be pivotally seated vin the grooves.` The ends of the' arms' 39` and 41, when in posit-ion embrace the upperportions of the (zo-operating form sections and each is provided with a threaded journal 55 in which the shank kofl a thumb screw 57 engagesf The end of the thumb screw bears upon a casting 59 which ori'ns aseat Jfor receiving the end of the shank. This casting is securedfto' the vi'orin section within a U-'shaped angle iron 29 and'vertically above lthe tie rod aperture33. Byv adjusting the thumb screw 57 the Vform sectionsinay be quickly adjusted to: vertical position, the upper edges of the co-operating sections being `held vin spaced relationship in Vthe notches 53 and the thumb screws A'providing a means for rotating the Vforni sectionsv in the' 'notches until vertical position is reached.'

terial and, since theY lat-ter Y' is poured between the forms in a plastic condition, will cause a transverse groovev to be limpressed.

across the top of the wall. -The rounded surface 1610i the bar is 'such' thatthe groove 63 formed by the bar has a shape corresponding with the 'contour ofthe tie rod 17,v that is to say, is adapted to receivethe tie'rod when` the vforms are replaced for 'the purpose of supporting the'succeeding course. Y

the top ofthe course Vby the clamp bar 39 Since the groove 63 is formed in after the latter :has been arranged in i'inal adjusted position, it will have a 'definite 'relation -to` thebposition ofthe .form and consequently to the surfaces'yof the wall. The parts areA arranged sothatthe vbar 39 Cil is vertically above and parallel to the tie rod'17 when the forms are in arranged position, and consequently, when the tie rod is arranged in the groove,the forms will automatically assume a proper relation to the top of the wall. The forms are thus adapted to align themselves upon the Wall when they are placed-in position to receive the building material, the only necessary adjustment being manipulation of the thumb screws 57 to bring the forms into plumb. I have shown, on the drawings,

form sections having two tie rods per section, but it will be understood that any convenient number of rods may be used.

The forms may be removed from the Wall after the course is set by first removing the clamps 19, and then withdrawing the tie rods 17 from the grooves in which they were arranged when the forms were iirst positioned upon the wall. The tie rod leaves a cylindrical hole G5 through the Wall, which may be filled with wooden plugs to which urring strips may be conveniently attached, or the holes may be plugged With fresh buildinomaterial after the Wall has been completed. c
